The invention aims at disclosing a vehicle lifting machine unlocking system and a lifting height control method, and relates to the technical field of vehicle lifting machines, the vehicle lifting machine unlocking system comprises two lifting platforms which synchronously lift and are arranged in parallel, and a first lifting assembly and a second lifting assembly are symmetrically arranged; the first lifting assembly comprises a first connecting rod assembly, a first hydraulic cylinder and a first locking assembly; the first hydraulic cylinder comprises a cylinder barrel, a telescopic rod and a U-shaped frame, a pull rope sensor is arranged at the end of the telescopic cylinder, a pull rope extending out of the pull rope sensor is connected to the cylinder barrel, and the first hydraulic cylinder always drives the lifting platform to ascend and descend through a first connecting rod assembly in an inclined mode. The locking air cylinder drives the second locking piece to be close to or away from the first locking piece, and the lifting device has the technical effects that the first hydraulic cylinder always drives the lifting platform to ascend and descend through the first connecting rod assembly in an inclined mode, and the lifting height of the lifting platform is controlled through the length of a pull rope; and locking or unlocking of the first hydraulic cylinder is achieved through the locking air cylinder, and the structure is reliable.
本发明的目的在于揭示一种车辆举升机解锁系统及举升高度控制方法,涉及车辆举升机技术领域,包括同步升降且平行设置的两个举升平台第一举升组件和第二举升组件对称设置;第一举升组件包括第一连杆组件、第一液压缸及第一锁止组件;第一液压缸包括缸筒、伸缩杆及U型架,在伸缩缸端部设置拉绳传感器,拉绳传感器伸出的拉绳连接于所述缸筒,第一液压缸始终以倾斜方式通过第一连杆组件驱动所述举升平台升降;所述锁止气缸驱动所述第二锁止件靠近或远离所述第一锁止件,技术效果:第一液压缸始终以倾斜方式通过所述第一连杆组件驱动所述举升平台升降,通过拉绳长度控制举升平台的升降高度;通过锁止气缸实现了第一液压缸的锁止或解锁,结构可靠。
